PCI_E1~5: PCIe Expansion Slots
PCI_E1: PCIe 4.0 x16 (From CPU)
PCI_E2: PCIe 3.0 x1 (From B760 chipset) 
PCI_E3: PCIe 4.0 x4 (From B760 chipset) 
PCI_E4: PCIe 3.0 x1 (From B760 chipset) 
PCI_E5: PCIe 3.0 x1 (From B760 chipset) 
 
Important
 
If you install a large and heavy graphics card, you need to use a tool such as MSI  
Graphics Card Bolster to support its weight to prevent deformation of the slot.
 
When adding or removing expansion cards, always turn off the power supply and 
unplug the power supply power cable from the power outlet. Read the expansion 
card’s documentation to check for any necessary additional hardware or software 
changes.
SATA_5~8: SATA 6Gb/s Connectors
These connectors are SATA 6Gb/s interface ports. Each connector can connect to one 
SATA device.
 
Important
 
Please do not fold the SATA cable at a 90-degree angle. Data loss may result during 
transmission otherwise.
 
SATA cables have identical plugs on either sides of the cable. However, it is 
recommended that the flat connector be connected to the motherboard for space 
saving purposes.
